Multiple offers?

I have an offer from a company I would love to join. I was not looking for change actively but a friend recommended her company and things moved fast. I have seen multiple posts on blind where an offer was rescinded by the company. It made me think if I am taking a risk by not having other options available. Also I might be leaving some money on the table by not checking out what I would have got if I tried more. I have family commitments and that makes preparing for interviews a challenge. So trying to get a pulse on what you do.
